SBVLC: Secure Barcode-based Visible Light Communication for Smart phonesKamal Spring
As an alternative to NFC technology, 2D barcodes have been increasingly used for security-sensitive applications including payments and personal identification. However, the security of barcode-based communication in mobile applications has not been systematically studied. In this paper, we propose SBVLC - a secure system for barcode-based visible light communication (VLC) between smart phones. We formally analyze the security of SBVLC based on geometric models and propose physical security enhancement mechanisms for barcode communication by manipulating screen view angles and leveraging user-induced motions. We then develop two secure data exchange schemes. These schemes are useful in many security-sensitive mobile applications including private information sharing, secure device pairing, and mobile payment. SBVLC is evaluated through extensive experiments on both Android and I OS smart phones.
In our application we have implemented the idea of QR code as password verification to overcome all the hacking issues. We have two modules as banker and the user. In the user module there will be two categories they are shopping and paying bill. In the shopping section user will shop the product and enter the card and bank details and send request to the banker regarding the transaction purpose. And in turn the banker module there are two categories they are the create OTP and the send OTP details. The banker will check the details of the user request regarding the purchase and all the card and balance details and prepare a password in the form of QR code. The password will be I the form of QR code and will be sent to the user through the mail service to the user personal mail id. In turn the user will pay the bill by loading the QR from the mail and scanning. On scanning the password will generate if the password matches with the banker details the transaction will become successful. Thus password hacking, key logging and eavesdropping issues will be overcome.
The document provides an overview of bar code technology and its uses and benefits. It discusses how bar codes work by encoding data in varying widths of black and white bars that can be scanned electronically. Bar codes allow for fast, accurate, and efficient data entry. The document outlines common applications of bar codes in retail, warehouses, healthcare, transportation and more. It also discusses the components needed for a bar code system and provides an example of how bar codes have improved operations at a library by streamlining check-in/check-out processes.

Zigbee Based Indoor Campus Inventory Tracking Using Rfid ModuleIJERA Editor
This document summarizes an RFID and Zigbee-based indoor campus inventory tracking system. It describes how RFID tags attached to objects can be identified and tracked using RFID readers. Zigbee modules are used to wirelessly transmit inventory data from the readers to a central server. The system uses passive RFID tags powered by electromagnetic fields from readers. When a tagged object enters the read range, its data is transmitted via Zigbee to allow centralized tracking of inventory across a campus.
RFID is a technology that uses radio waves to automatically identify objects. RFID tags attached to objects are scanned by an RFID reader to transmit data wirelessly. A basic RFID system consists of an antenna that emits radio signals, a transceiver that controls data acquisition and communication, and a transponder tag that contains identifying information transmitted to the reader. The document discusses applications of RFID technology including tracking objects and automating processes like access control and parking systems.
Automatic identification and data capture (AIDC) technologies electronically collect data without manual entry. This includes barcode, RFID, NFC, and biometrics. RFID uses radio waves to automatically identify tags attached to objects and track them. An RFID system has tags, a reader, and antenna. Tags can be active (battery-powered) or passive. RFID operates at various frequencies and is used for applications like supply chain management, asset tracking, and electronic toll collection due to advantages like non-line-of-sight scanning and tagging of multiple items simultaneously. NFC is a short-range wireless technology that allows data exchange between devices when touched together, and has modes for card emulation, peer-to-
Automation of shopping cart to ease queue in malls by using RFIDSudher Sun
RFID technology is proposed to automate the shopping cart and billing process in malls. The current barcode system requires line of sight scanning and is slow. The proposed system uses RFID tags embedded in products that can be automatically read by an RFID reader in the cart from a distance. As shoppers add items to their cart, the tags are read and the items and running total are displayed. This allows for a more efficient checkout where the total is already known without additional scanning. The system architecture uses an RFID reader, microcontroller, Zigbee for wireless communication, and an LCD for display. Benefits include simplified billing, increased speed, and an improved overall shopping experience.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

(static) background a highpass filter is applied. This
filter compares the contrast in the image and only
allows `high' values to pass through (depending on a
pre-set value). As a result only the touched spots will
be visible. Depending on the used diffuser and
infrared LEDs the result might show weak blobs, in
this case we can add a scaler filter to amplify the
brightness of the blobs. Finally, the rectify filter is
applied resulting in clear blobs ready for tracking. It
is used to filter out noise and reduce the gray scale
image to a black and white image only displaying
the actually touched areas.
An example of the Touchlib image processing
results can be found in Figure 5.

3.1.2 Choosing an appropriate camera device
When choosing a camera it is
recommended to find out which sensor is used and
whether the data sheets are available for this sensor.
Whilst high-end consumer USB cameras are capable
of transmitting images of VGA resolution (640X480
pixels) at reasonable frame rates, they often
introduce latency. Because this reduces the
responsiveness of the multi-touch devices, it is
recommended to use a FireWire based camera
instead. Depending on the size of the display and the
projected image it is recommended to use at least a
camera running a VGA resolution because of Fig. 5. Example of Touchlib filter chain using
precision. The frame rate should be at least 30 front side illumination

Touchlib prepares the events to be triggered. First
Touchlib walks through the list of currently active
blobs. If a blob is new in the current frame (it did not
match with a blob in the previous frame) it will
contain an ID with the value -1. In that case a new
ID will be generated and assigned. After the
assignment a “touch event” of the blob will be
dispatched. If a blob in the current frame matches a
blob of the previous frame, it will use the same
identifier of the previous frame. Depending on the
amount of movement an update event will be
dispatched. If the delta of movement is higher than

assume to be correct. In this case instead of an
update event a “touch event” is dispatched instead. If
the delta of movement from the current and the
previous frame is below the value of
minimumDisplacementThreshold, no update event
will occur. After Touchlib processed the list of
currently active blobs, it compares the list with the
blob list of the previous frame. If a blob was active
in the previous frame but has not been found in the
current frame, the blob is marked for deletion and a
“touch up event” will be dispatched.

tracker. Currently image processing is done on the
CPU. In order to reduce the load on the CPU it is
possible to use graphics processing units (GPU) for
image processing. The current blob tracker used in
Touchlib is not scalable. Depending on the used
hardware, Touchlib will fail to track fifty or more
blobs in real-time. A smarter algorithm would not
only take the distance into account but also the
region and direction of a blob. It would also be
interesting to use the GPU for blob tracking. Based
on our own experiences the touch surface should be
improved. The friction with the acrylic makes it hard
to use the system for a longer period of time.
